Solar activity was low. Regions 4378 (N16W44, Cso/beta), 4381 (N08W11, Eai/beta), and 4386 (N15W76, Cao/beta) exhibited slight development while the remaining regions were either stable or in decay. A CME associated with a filament eruption centered near S20E30 at around 06/0428 UTC is likely to arrive as a glancing blow on 10 Mar. .Forecast... Solar activity is expected to be at low levels, with a slight chance for M-class (R1-R2/Minor-Moderate) flares through 09 Mar. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to reach high levels on 07-09 Mar. The greater than 10 MeV proton flux is expected to continue at background levels through 09 Mar. Solar Wind .24 hr Summary... The solar wind environment was consistent with a solar sector boundary crossing followed by the onset of negative polarity CH HSS influences. Total magnetic field strength reached 11 nT, and the Bz component varied between +6 and -8 nT. Solar wind speeds ranged between 325-385 km/s throughout the period. The phi angle transitioned from positive to negative at around 06/0900 UTC. .Forecast... Enhanced solar wind conditions are expected to persist through 09 Mar due to negative polarity CH HSS influences. Geospace .24 hr Summary... The geomagnetic field was at quiet to unsettled levels. .Forecast... The geomagnetic field is expected to reached active levels on 07-09 Mar due to negative polarity CH HSS influences.
